Copper Core PCB Production Record #CU-20260719-033

This order consisted of five single-layer copper core PCBs produced as panels, each measuring 123.2 × 83.8 mm with a total thickness of 2 mm. The 380 W/mK copper core required dedicated material preparation, copper core processing, and thermal via implementation to ensure effective heat dissipation. Base 2 oz copper was supplemented with thick copper electroplating and controlled etching to accurately produce the 5/5 mil track and spacing on this heavier copper design.

Matte black solder mask was applied without silkscreen, followed by OSP surface finish and anti-oxidation treatment to protect the exposed copper. These steps, together with precise plating control, preserved feature integrity across the panels while meeting the specified tolerances for this copper core PCB. Full electrical testing confirmed circuit continuity and isolation on every board.

The complete sequence from engineering review through heavy copper plating and final inspection extended over 12.2 days. Attention to etching uniformity and thermal via plating delivered consistent thermal performance and mechanical stability suited to high-power applications.
